Diffusion Flashcards
What is diffusion?
Diffusion is the movement of particles from an area of higher concentration to an area of lower concentration.
How do gas particles behave during diffusion?
Gas particles move at high speeds and collide with the walls of their container, allowing them to diffuse into available space.
How does diffusion occur in liquids compared to gases?
Diffusion occurs in liquids, but it takes place much more slowly than in gases.
Does diffusion happen in solids?
No, diffusion does not happen in solids.
What happens to particle movement as temperature increases?
As the temperature increases, particles move faster.
What is demonstrated by the example of blackcurrant juice in water?
The example demonstrates diffusion in a liquid, showing how particles spread over time.
What kind of movement is diffusion?
Random
What does diffusion explain in living things?
Diffusion explains how the food you eat gets into your bloodstream.
What happens to food after a meal?
Food passes into your stomach where large particles are broken down into smaller particles.
What can smaller particles do after being broken down?
Smaller particles can diffuse through the walls of the intestines into the bloodstream.
What should you not do with the juice or its solution made in a laboratory?
Do not drink the juice or its solution if it has been made in a laboratory.
